The rapidly evolving blockchain infrastructure landscape has taken another leap forward with ZkLink, a decentralized trading platform leveraging zero-knowledge rollup technology, securing $10 million in a strategic funding round. Headlined by Coinbase Ventures — the investment arm of leading crypto exchange Coinbase — this capital infusion marks growing institutional confidence in scalable, cross-chain solutions. The funds will accelerate ZkLink’s development as it prepares for its highly anticipated mainnet launch in the third quarter of 2025.
ZkLink is engineered to solve one of the most persistent challenges in decentralized finance (DeFi): seamless and efficient cross-chain trading. By building on zero-knowledge (zk) rollups, the project combines high throughput with strong security guarantees, offering users the speed and responsiveness typically associated with centralized exchanges — but without sacrificing decentralization or custody control.
The Rise of Zero-Knowledge Rollups in Blockchain Infrastructure
Zero-knowledge rollups are emerging as a cornerstone of Ethereum’s scaling roadmap. These Layer 2 solutions process transactions off-chain and submit cryptographic proofs to the mainnet, drastically reducing gas fees and congestion while maintaining security. Unlike optimistic rollups, which assume validity unless challenged, zk rollups use mathematical proofs to verify every transaction upfront — enabling faster finality and stronger trust guarantees.
ZkLink harnesses this technology to create a unified trading layer that connects multiple blockchains. Instead of siloed ecosystems, developers can build decentralized applications (dApps) that interact seamlessly across Layer 1s like Ethereum, Solana, and Bitcoin sidechains, as well as Layer 2 protocols.
This interoperability is critical for the next phase of DeFi growth. As more assets and user activity spread across chains, fragmented liquidity becomes a major bottleneck. ZkLink aims to eliminate this by aggregating order books and enabling trustless asset swaps without relying on bridges — which have historically been vulnerable to exploits.

Building a Decentralized Trading Ecosystem with zk Technology
At its core, ZkLink offers a modular infrastructure stack designed for developers. Using its APIs, teams can integrate advanced trading functionalities into their platforms — including order book DEXs, NFT marketplaces, and derivatives protocols — all powered by zk-based validation.
Co-founder Vince Yang emphasizes the user experience transformation enabled by ZkLink:
“ZkLink plays a crucial role in shaping the future of the crypto landscape by leveraging the potential of ZK technology. For newcomers to the field, envision a scenario where decentralized finance trading delivers comparable user experience, efficiency and speed as centralized exchanges, but also provides the advantages of being trustless and non-custodial.”
This vision aligns with broader industry trends toward composable, developer-friendly protocols. With Ethereum’s ecosystem expanding through modular architecture and rollup-centric scaling, projects like ZkLink are positioned to become foundational building blocks.
The upcoming mainnet launch will be preceded by two key community initiatives: the “Odyssey” campaign, aimed at engaging early adopters and contributors, and the “Dunkirk” asset withdrawal test, a stress-test simulation designed to validate system resilience under real-world conditions. These efforts underscore ZkLink’s commitment to transparency and security ahead of full deployment.
Strategic Investment Momentum Amid Market Recovery
While crypto venture funding plummeted after the 2022 market downturn, infrastructure projects have remained resilient. According to insights from Andreessen Horowitz’s annual crypto report, zero-knowledge technology continues to attract significant interest due to its long-term scalability and privacy benefits.
ZkLink’s $10 million raise brings its total funding to $18.5 million since inception. In addition to Coinbase Ventures, the round included participation from Ascensive Assets, SIG DTI, BigBrain Holdings, Efficient Frontier, and other institutional backers. This diverse investor base reflects strong confidence in both the team’s technical roadmap and the growing demand for cross-chain liquidity solutions.
The timing is pivotal. Just months before ZkLink’s planned launch, competitors such as Polygon and Matter Labs debuted their zk-EVM mainnets within days of each other in March 2025, signaling intensifying competition in the zk space. However, rather than focusing solely on EVM compatibility, ZkLink differentiates itself by prioritizing multi-chain aggregation and native support for diverse asset types — including NFTs and fungible tokens — across heterogeneous networks.
